> and current date and time. It then reads a file from the tape describing a series of file sets (mount points)
> starting with /, /usr and /var. For each mount point, the space required and the type are specified in the file.
> The install program then allocates space after a first-fit policy, and tries to avoid putting two filesets of the same
> type on the same disk (This is done to separate Oracle tablespaces and redo logs if necessary). The tape of
> course just holds a series of vdumps ordered by the description file. Swap space is divided evenly among all
> selected disks, and the root dump is placed on all 'a' partitions to provide alternative boot disks. All references
> in /etc/fdmns, /etc/fstab etc. are resolved by this program. And it is just 800 lines of sh+awk in one script
> to put on the bootable disk. If anyone are interested, I can send you a copy.
